Abstract

The invention discloses a primary-efficiency filter screen device for a fresh air fan, comprising first and second stepper motors, a drum, a support frame and a primary-efficiency filter screen. On the stepping motor, the support frame is arranged between the two drums, one end of the primary filter screen is rotatably connected to the drum of the first stepping motor, and the other end is rotatably connected to the drum of the second stepping motor, The primary effect filter screen can be moved and laid on the support frame tightly, and the primary effect filter screen can be moved from the drum of the first stepper motor to the drum of the second stepper motor. The effective filter device can increase the expansion area of ​​the primary filter and enhance the filtering effect.

Description

technical field [0001] The invention relates to the field of fresh air fans, in particular to a primary filter screen device for fresh air fans. Background technique [0002] The fresh air fan introduces the outdoor air with high oxygen content into the room through the fan to reduce the rising CO2 in the indoor closed environment. 2 value. Considering the different levels of dust and other impurities in the actual outdoor air, it is necessary to add a dust filter to achieve air filtration. Fresh air fans generally have primary effect, medium effect, high efficiency or other filters to achieve this purpose. [0003] Generally, there are two types of filter screens: flat type and discounted type. Since the discounted filter can better realize more filter screen area per unit volume, the discounted filter screen is adopted by many models. However, in order to pursue a larger expansion area, it is also necessary to enlarge the dimensions of the length, width, and thickness o...
